We had lots of action at the Pittsburgh peregrine nests overnight.
Tasha2 at the Gulf Tower laid her first egg of 2010. Click on her photo above to see a nighttime image of her with the egg, captured by Marianne Atkinson before 5:00am. As Marianne watched, Tasha carefully moved the egg to the right and into the scrape. In the nighttime image, the egg is the white circle and Tasha is bending her head down with her tail in the air.
Meanwhile at the Cathedral of Learning, Dorothy laid her third egg as shown below.
The eggs are white in nighttime pictures because they’re made visible using infrared light. In daylight the eggs are a deep red-brown color. Yes, that’s the egg between Tasha’s feet.
So why do Dorothy’s eggs look pink on the streaming cam at Pitt? Because the infrared light is very close and the camera can see infrared, even during the day.
Don’t miss the action!

Now that Dorothy has laid her third egg she will likely begin incubation. See the Peregrine FAQs for more information.
